4x Bulb T5 HO Combo Help

Hey guys. I'm fairly new to the whole lighting scene and thought I'd ask for some help before I placed an order to replace my 4x T5 HO bulbs. After having done a little bit of research around the site about what others have used for their 4x bulb combo, I think I have a general idea about what I want to purchase (below). I'm trying to shoot for a more blue/purple hue compared to my previous combo (below) of bulbs that came stock with the purchase of my lighting unit.



I just want to know what you guys think of my bulb choices, as well as any advice/recommendations/etc. you may have, comparing my previous bulb combo with my current goal of shooting for a more blue/purple hue. Also, I don't want to stress out my corals by completely switching up the type of bulbs I use, and I'm unsure if this is even possible since I'm still staying with T5 HO bulbs? Like I said, I'm really new to the lighting scene and would appreciate any and all help - thanks in advance!
